Product details
Overview
74VHC32D-Q100 from Nexperia is a quad 2-input OR gate IC in SO14 package, qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with CMOS input levels, 5.5 V max supply, and propagation delay as low as 2.8 ns (VCC = 4.5–5.5 V, CL = 15 pF). It serves as a logic-level combiner in body control modules, powertrain interface circuits, and infotainment signal routing.
For engineers reviewing the 74VHC32D-Q100 datasheet, 74VHC32D-Q100 pinout, 74VHC32D-Q100 application, or 74VHC32D-Q100 equivalent, key selection criteria include automotive temperature range compliance, TTL-compatible pinout with Schmitt-trigger inputs, balanced propagation delays across all four gates, and SO14 package suitability for reflow-soldered automotive PCBs.
Technical Context
This device implements four independent 2-input OR logic functions using high-speed Si-gate CMOS technology, fully compliant with JEDEC Standard No. 7-A and pin compatible with LSTTL. Its inputs accept voltages up to 7.0 V regardless of VCC, and all inputs feature Schmitt-trigger action for noise immunity on slow-rising signals.
The 74VHC32D-Q100 operates with CMOS input thresholds (VIH ≥ 3.85 V at VCC = 5.5 V; VIL ≤ 1.65 V), delivers VOH ≥ 3.70 V and VOL ≤ 0.55 V under 8 mA load, and exhibits static ICC ≤ 40 μA at VCC = 5.5 V - enabling low-quiescent-power operation in always-on automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Four independent 2-input OR gates; each outputs HIGH if either input is HIGH. |
| Supply Voltage Range | 2.0 V to 5.5 V - supports 3.3 V and 5 V automotive domains without level shifting. |
| Propagation Delay | 2.8 ns typical (VCC = 4.5–5.5 V, CL = 15 pF) - enables timing-critical signal combining in <10 ns windows. |
| Input Thresholds | VIH ≥ 3.85 V, VIL ≤ 1.65 V at VCC = 5.5 V - ensures robust CMOS-level compatibility and noise margin >1.3 V. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cabin-located ECUs. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive assembly and handling requirements without external protection. |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small capacitive loads (<50 pF). |
Pinout & Package
SO14 plastic small outline package (SOT108-1), 14-lead, 3.9 mm body width, 1.27 mm lead pitch, with gull-wing leads suitable for automated optical inspection and standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A | Input A of Gate 1–4 | Primary logic input; accepts 0–7.0 V, Schmitt-triggered for hysteresis on noisy lines. |
| 1B, 2B, 3B, 4B | Input B of Gate 1–4 | Secondary logic input; identical electrical behavior to A inputs; no internal priority. |
| 1Y, 2Y, 3Y, 4Y | Output Y of Gate 1–4 | CMOS push-pull output; rail-to-rail swing; capable of sourcing/sinking 8 mA. |
| 7 | GND | Ground reference (0 V); must be connected to system ground plane for stable logic operation. |
| 14 | VCC | Positive supply; decoupling capacitor (100 nF) required within 5 mm for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across -40 °C to +125 °C ambient, including thermal cycling and HTOL stress. |
| Schmitt-trigger inputs | Provides ~0.3 V hysteresis per input, rejecting noise spikes <100 ns and enabling reliable operation on slow RC networks. |
| Overvoltage-tolerant inputs | Accepts VI up to 7.0 V independent of VCC - allows interfacing with 5 V logic even when VCC = 3.3 V. |
| Low dynamic power | CPD = 10 pF; enables sub-100 μW average power at 1 MHz toggle rate with 5 V supply. |
| Pin-compatible with LSTTL | Direct drop-in replacement for 74LS32 in existing designs, preserving PCB layout and signal routing. |
Applications
| Body Control Module (BCM) | Powertrain Control Interface |
|---|---|
|
Use Scenario: Combining door lock request signals from multiple switches into a single enable line for the central locking actuator driver. IC Role / Device Role / Timing Role: Logic-level OR gate aggregating asynchronous mechanical switch inputs with debounced timing.

IC Role / Device Role / Timing Role: Fail-safe combiner ensuring any single sensor fault triggers immediate diagnostic action. Use Value: Hardware-level fault detection with guaranteed <10 ns latency - faster and more reliable than software-based OR logic. |
| Infotainment System Audio Routing | ADAS Camera Power Sequencing |
|
Use Scenario: Enabling audio amplifier power-on when either Bluetooth stream or USB media playback is active. IC Role / Device Role / Timing Role: Wake-up signal aggregator driving enable input of a PMIC or discrete MOSFET gate driver. Use Value: Reduces standby current by 12 μA vs. MCU polling; eliminates wake latency from interrupt latency and ISR execution. |
Use Scenario: Generating combined "camera ready" signal only after both image sensor and ISP power rails are stable.

Use Value: Prevents boot failure due to race conditions; ensures deterministic power sequencing without FPGA or CPLD. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74VHCT32D-Q100 | TTL-compatible input thresholds (VIH = 2.0 V min), otherwise identical pinout, timing, and packaging. | Required when interfacing directly with legacy 5 V TTL outputs without level shifters. | Select when driving from 74LS/74F series or microcontrollers with weak 5 V drive capability. |
| SN74LVC32APWR | Lower VCC range (1.65–5.5 V), higher speed (tpd = 2.5 ns typ), but not AEC-Q100 qualified. | Limited to industrial or consumer applications; unsuitable for production automotive systems. | Use only for prototyping or non-automotive derivatives where qualification is not mandated. |
Compared with 74VHC32D-Q100, the 74VHCT32D-Q100 offers direct TTL interoperability at identical packaging and temperature rating, while SN74LVC32APWR trades automotive qualification for wider voltage support and marginal speed gain - making the original part optimal for certified automotive deployment.

FAQ
Is 74VHC32D-Q100 compatible with 3.3 V I/O systems?
Yes. The device operates down to 2.0 V supply and accepts input voltages up to 7.0 V regardless of VCC, enabling direct connection to 3.3 V microcontrollers while maintaining full logic functionality and noise immunity via Schmitt-trigger inputs.
What is the maximum capacitive load this OR gate can drive reliably?
It reliably drives up to 50 pF at 5 V supply with tpd ≤ 7.0 ns (CL = 50 pF, VCC = 4.5–5.5 V). For loads exceeding 50 pF, propagation delay increases linearly; derating curves are provided in Section 10 of the datasheet for precise timing budgeting.
Does this part require external pull-up or pull-down resistors on unused inputs?
No. Unused inputs may be tied directly to VCC or GND. Due to Schmitt-trigger action and defined VIH/VIL thresholds, floating inputs are electrically unstable and must not be left unconnected - internal clamping diodes do not eliminate risk of oscillation or excess current draw.
Can 74VHC32D-Q100 be used in place of 74LS32 in an existing design?
Yes - it is pin-compatible and functionally identical. However, verify that the existing 74LS32 load capacitance and fan-out requirements fall within the 74VHC32D-Q100's ±8 mA output drive capability and that VCC remains within 2.0–5.5 V. No PCB changes are needed.
